A friend of mine just got 18-40 years for arson. Funny thing is the eyewitness said in court it wasn't him and he passed a polygraph but they refused to drop the charges. The brilliant jury still convicted him because his ex-girl (the person who's car was burned up, and who's house almost caught on fire) claimed she saw burn marks on his face a few days after the fire. It would be funny if it wasn't so sad.
Moral of the story - stay far away from vindictive crazy bitches. I paid his $50k bond to get him out while he was on trial (got my $ back when he was convicted) and I'm paying for his appellate attorney. I've been on the other side and I know how important it is to have people helping you.
